Studying compressible inviscid flow over symmetric and supercritical airfoils is important because it useful to understand maximize aerodynamic performance in a range of industrial contexts. This study addresses the analysis for both time-dependent stationary scenarios. The primary goal these simulations' look at how different velocity variations affected certain airfoil parameters. Air utilized as material above airfoils. best fit simulations Spalart-Allmaras Turbulence model, which shows good agreement wider with published experimental data from other studies. COMSOL Multiphysics software used all analysis, angle attack 0°, temperature 288K, pressure 1bar that are constructed by importing file form excel file. On comparison flow, has better results on basis magnitude, pressure, vorticity shear rate rotation rate. converging faster than airfoil.
